Dear Bhas (and others),
I am with Deepak and Hani - and they have been recently working on Sound in
CLIx. So let us take the Bal Vaigyanik 7 chapter 4 on Sound.
Shouldn't you take the Bal Vaigyanik 8 chapter 4 on Machines?
The other chapters are:
BV6-4-Magnets
BV7-11-Games with Air
BV7-15-Light (+ page 20 on Playing with Shadows in BV6)
BV8-13-Looking at the Skies
Which ones should we select amongst these? If we look at the tab named
"Marathi Translation"in this document
<https://docs.google.com/spreadsheets/d/120t9PkQdo5hnTMkfTMJA2WoDWPQTPKoRj-CEnb8Q3g8/edit?usp=sharing>,
we see that Light and Magnets are there in both 6th and 7th standard
textbooks of Maharashtra board.
Please let us know about your choice.
Best,
Anish
